Going back in time a little. Right after Lensa left the trio alone at the city market.
"Wow, dude. I think the elf girl is falling for you. She was telling you she visits Moonview lake at the full moon and today would be no different. That's an invitation for you to join her if you ask me."
Eren gave a firm pat on Ken's shoulder after he got back to his team. Almera also smiled at Ken before saying:
"Ken, I think you should consider joining that beautiful elf. An elf's affection is not easy to gain."
The E-Ranker also encouraged the boy to go on a date with Lensa. But the boy himself wasn't sure. He expressed his concerns:
"I'm not sure if you've noticed, but look at this city and its people. The Faeruns carry a very large weight around here. It would be bad for all of us if things go wrong between me and Lensa."
